The lights work only with the ignition on, unless otherwise stated.
On models fitted with right-hand steering, the position of some of the controls
differs from that shown in » Fig. 28 on page 55. The symbols which mark the
positions of the controls are identical.
Keep the headlights lenses clean. The following guidelines must be ob-
served » page 207 , Headlight lenses .
WARNING■
The activation of the lights should only be undertaken in accordance with
national legal requirements.■
The driver is always responsible for the correct settings and use of the
lights.
■
The automatic driving lamp control only operates as a support and does
not release the driver from his responsibility to check the light and, if necessa-
ry, to switch on the light depending on the given light conditions. The light sensor cannot, for example, detect rain or snow. Under these conditions we
recommend switching on the low beam or fog lights!
Note
■ If there is a fault in the light switch, the low beam comes on automatically.■The headlights may mist up temporarily. When the driving lights are switched
on, the light outlet surfaces are free from mist after a short period, although the
headlight lenses may still be misted up in the peripheral areas. This mist has no
influence on the life of the lighting system.■
The instruments are also illuminated when the side light, low or high beam light
is switched on. The brightness of the instrument lighting can be activated or de- activated in the Infotainment » Operating instructions for Infotainment , chap-
ter Vehicle settings (CAR button) .
